How JSON to TOML conversion works

TOML (Tom's Obvious Minimal Language) is a configuration file format. JSON objects map to TOML [tables], arrays of objects become [[array of tables]], and scalar arrays use inline syntax key = [1, 2, 3]. Strings are quoted and special characters are escaped.

For the reverse conversion, use the TOML to JSON Converter. To format existing TOML, try the TOML Formatter. To convert between JSON and YAML, see JSON to YAML Converter.
